Hi Shiva,
I thought of the following method to encourage publishing the paper (especially in light of the recent Elsevier boycott): mention in your list ONLY the papers that are publicly accessible.
Dan.

We have a long way to make the community of TCS “open-access”.
If we don’t make steps towards there, it won’t happen.
I do not question the various reasons (I would really call it excuses) why authors wouldn’t post the papers – now, before submitting, or never.
BUT: you sent the paper to STOC and it got accepted? POST YOUR PAPER!
If not, your paper won’t be in the list of files with pdfs on this blog, that’s it.
Dan.

I second Dan!
This list is a compilation of PDF’s. If someone just wants to see the list of accepted papers, they can go to the STOC site instead.
Another alternative is to have two lists, one only with those papers available online, and the other like the one you have now.
